SpO2 is in blank on Inspire 3

[MarinaMV]

I got my Inspire 3 on Thursday and have been wearing it every day since then. The SpO2 has been blank the entire time. I don’t normally sleep with my trackers as I find that uncomfortable, but I tried that last night to see if it needed a night cycle to start working. Still nothing.

Hi there, @MarinaMV. Welcome to the Community Forums. Thanks for the details provided in your post about the issue with your Inspire 3. I understand where your concern is coming from. 

Thanks for confirming that you're tracking your sleep. Please also take the following into consideration:

• Your device doesn’t retroactively measure your SpO2 values. When you start using Fitbit SpO2, you’ll see dashed lines until after your next sleep session.
• You must get at least 3 hours of quality sleep. Data is only collected when you’re still. If you move a lot during your sleep or the sleep session is too short, you might not get SpO2 data.
• Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using an SpO2 clock face or app.
• You must sync your Fitbit device with the Fitbit app before the tracker shows your SpO2 data. Note that it may take around an hour for your SpO2 values to appear after you sync your device. For troubleshooting syncing, see Why won't my Fitbit device sync?
• Turning off SpO2 app permissions can cause the feature to stop functioning. Please make sure SpO2 app permissions are granted.  For instructions on adjusting permissions, see How do I install and manage apps on my Fitbit device?
• Your Fitbit device must be able to consistently track your SpO2 data:
  • Wear your device slightly higher on your wrist.
  • Make sure your device is in contact with your skin.
  • Your device should be snug but not constricting.
  • Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.

Hope that helps.
